Marcus, the Enhance RS88 has a built in RAID controller, so you don't need to have a second one with an Areca or a Attotech. You can just use a SAS card like the LSI SAS 1068E which costs around $120. If you want to use the Areca or Attotech Raid controllers, then you can use the RS8 MS for around $756 or RS16 JS. Enhance has a compatibility matrix and includes seagate 1.5tb and also Attotech R380 and Areca 1680x. You can always contact them and ask if they have tested a config with the exact raid controller/drives/Raid level you are thinking of using. I have a friend who had issues with Areca and Seagate 1.5tb drives. Not sure if that issue has been resolved, may be worth contacting Areca to be sure.
